EXCELSlOR-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 410,564, datedSeptember 3, 1889. Application filed January 17, 1889. Serial No.296,684. (No model.)

To all whom, it may concern:

Be it. known that 1, CHARLES G. SMITH, a citizen of the United States,residing at Detroit, in the county of \Vayne and State of Michigan, haveinvented a new and useful Excelsior-Machine, of which the following is aspecification.

My invention relates to improvements in that class of excelsior-machinesin which the knife runs in a frame; and it consists in placing the knifein a frame operating in conjunction with the carriage or feed forpropelling the block, and the lever and bars for regulating the speed ofthe carriage or feed.

The objects of my improvements are, first, to increase the production ofexcelsior; second, to save labor, and, third, to reduce the cost of thiscommodity. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a sectional view of theentire machine as it appears after the block is inserted in frame ofcarriage. Fig. 2 is a rear view of the carriage or block frame. Fig. 3is a rear view of the machine. Fig. 4 is a front View of the carriage orframe. Fig. 5 is a view showing the knives in a position to cut. Fig. 6is a front view of the large knives. Fig. 7 is a sectional view of theknives. Fig. 8 is a top view of the knifecase. Fig. 9 is a top View ofthe small knife or slitter. Fig. 10 is a side view of the small knife orslitter. Fig. 11 is a front view of the large shavingknife. Fig. 12 is aback view of the large shaving-knife. Fig. 13 is a view showing theknives, large and small, sliding into position in the frame. Fig. 14 isa back View of the case, looking from the rear of the machine, showingthe knives, drive-wheel, pitman, and brace. Fig. 15 is a view of theupright bar. Fig. 16 is a view of the weight which actuates theblock-carriage.

Similarletters refer to similar parts throughout the several views.

X is a sectional knife composed of A, B, G, C, and G. The shaving-knivesA (see Figs. 11 and 12) and the slitting-knivesB (see Figs. 9 and 10)are made in any number of sizes, and numbered 1, 2, 3, &c., the onlydifference in the sizes of the knives being that No. 2 is the011ehundredth part of an inch, more or less, thicker than No. 1,according to the thickness of the shaving desired, thus causing the edgetof shaving-knife A and the point N of slittingknives B to project outover-No. 1 suflicientl y to make the thickness of shaving desired, knifeNo. 3 being the same degree thicker than No. 2, and so on up to thehighest number. (See Fig. 7.) A and B are slid into the groove in frame0 on top of plate 0. (See Fig. The knives A and B may be insertedalternately, as shown in Figs. 5, 6, and 7, or one slitting-knife B maybe used for one or more of the shaving-knives A. After the desirednumber of knives A and B are inserted in frame C,plate or cross-head Gis set on top and secured by means of bolts or screws, which hold theknives firmly in position; or a thumb-screw K, passing through plate G,the lower end of screw resting upon top of upper knife, may or may notbe used, as it forms no part of my invention and is not necessary to theproper working of the other parts, the shaving-knives being formed withgroove or opening a to allow the shavings to pass through. Thiscombination of plate 0', frame 0, the shaving and slitting knives, andthe top plate G constitutes my exeelsior-knife X, which in this machinereciproeates in an iron frame set in standard D, but is designed to runin either a vertical or horizontal position. The slitting-knives B passover the block first and slit the surface of the block into narrowstrips any desired Width, and knives A, following, shave oif shavingsthe desired thickness. These thin narrow strips pass out through grooveor opening a as excelsior, ready for packing into bales. Knife X isactuated by the pitman F, one end of which is attached to cross-bar Land the other end to the Wheel E, which is actuated by pulley '1; onshaft 00, belt f supplying the power. Any other suitable gearing may besubstituted for E, w, 1,)", and L, this shown being of the simplestconstruction and forming no part of my invention.

The block carriage or feed is formed by cog-bar U and frame N, cast orframed to gether, U resting upon bottom of groove in table supplied withroller 1' and propelled by h, attached to pulley or wheel and bar 9' bycord or chain t to cog-wheel T, set above cogbar U, and in addition topropelling carriage weight it holds the bar U firmly in place,

giving it a smooth steady motion. Crank Z is used to run the carriageback into position to receive fresh block Q. r, U, and T are fitted intoand run in a groove running lengthwise of the table, (see Fig. 3,) whichgroove runs the Whole length of the table.

g is an iron plate slightly raised above the surface s of the table 19,upon which the block Q rests while the knives are descending.

7c is an iron plate fastened to the standard above the block, whichhelps to hold block firmly in position while the knives pass upward.

Bar B is attached to standard N by means of a hinge and rests upon pointm in slot in brace S. The teeth or cogs are so set that it passesforward on being slightly raised, but sets firmly when pressed backwardand helps to hold the block firmly in position.

P is the plate or frame forming the upper part of block-frame andattached to the carriage by a hinge, and, like the bottom of theblock-frame, is supplied with spurs 1), together forming a clamp whichholds the block firmly in the frame.

0 is the lever to plate P.

The speed of the carriage is regulated by bar Y and leverW. WV isattached to center brace S by a hinge. To the lever \V is attached barY, which has slots e, (see Fig. 15,) with shoulders to hold flange onbar R, which passes through it. The point of bar Y rests in the teeth ofbar U. When knives move upward, the point of lever W is caught by top ofknife 0 and carried up to dotted lines. This raises the point of bar Yout of teeth of bar U, and raises bar R above the point m. The weight hthen forces the carriage forward until the block Q rests against theplate 0 in position for knivesB and A. As soon as the knives begin todescend, lever W drops to the bottom of slot Z. This allows bar R andthe point of bar Y to fall into position, holdin g the block back untilthe knives have passed upward into position. Catch y is fastened to thetable I) by hinge d, and holds carriage in position when run back bycrank Z and while slab is being removed and fresh block Q inserted, asshownin Fig. 1.

I am aware that eXcelsior-machines have been made running a singleshaving-knife and slitting-knife in a vertical or horizontal position. Itherefore do not claim such a combination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, in an eXcelsior-machine, of the frame 0, to receivethe plate 0, the shaving-knives A, and the slitting-knives B, the plate0, fitted in the frame 0 at the bottom to support the knives, theshavingknives A, fitted in the frame 0 and resting on top of the plate0', the slitting-knives B, fitted in the frame 0, resting on top of oneor more of the shaving-knives A, the plate or cross-head G, set on andfastened at top of the frame 0 to retain the knives in place, allsubstantially as set forth.

2. In an eXcelsior-machine, the combination of the frame 0 and the plate0, to receive the shaving-knives A and the slittingknives B, theshaving-knives A, the slittingknives B, the top plate or cross-head G,to

retain the knives in the frame 0, the standard D in which the frame 0reciprocates, and the t.ble Z), which supports the block to be cut up,all substantially as set forth.

3. The combination, in an eXcelsior-machine, of a table or bench 19,provided with groove, the groove running full length of table, in whichthe cog-bar U, supporting the carriage-frame N, runs, the cog-bar U,supporting carriage, the carriage-frame N, to carry the block, propelledand held in position by the cog-wheel T, the cog-wheel T, the bar 1',and the weight 71, which forces the block toward the knives,substantially as shown and set forth.
